This jumper is only accessible by removing the right side panel (see above) and sets whether the ramp input is in master or slave mode. It is factory set to be in MASTER MODE. In SLAVE MODE (jumper off) the RAMP signal is generated externally and input through the back panel RAMP I/O port. In MASTER MODE (jumper on) the ramp is generated internally and is sent out to the RAMP I/O port for driving other D2-125 Laser Servos configured in SLAVE MODE. ​

-

The slave ramp is multiplied by about -5x (at slave Ramp Amp maximum) ​from the master ramp input and then the DC offset is applied.

+

The amplitude of the slave ramp is about -5x of the master ramp input (at slave Ramp Amp maximum). The DC offset is applied ​after amplification.
